He is the tournament's top ball carrier and Wales' second highest in the tackle count but he reckons there is more to come.
"There are areas to work on - everywhere and they are just stats," said Faletau.
"It could be just metre carries or just picking the ball up, - that's a carry I guess.
"It's going okay for me, myself and the team."
Faletau will once again line-up next to Ryan Jones and Justin Tipuric in the Welsh back-row
"They are great," added Faletau.
"Tipuric's been playing well and then you've got Ryan who is just a great leader who gets everyone together and they stick together.
"They are all different and have different qualities.
"There's the right balance their still. Ryan with all his experience can only do the team good."
Wales will learn today if Sergio Parisse will be available to captain Italy. The Stade Francais star was sent off over the weekend for allegedly insulting a match referee in the Top 14.
But Faletau hopes to go up against the inspirational skipper and expects a fierce battle against the Azzurri.
"I'm not sure of the case or what he has done or not," said Faletau.
"We are preparing for him playing.
"He's a great player, physically strong. He carries well and leads well too so he's great for their team.
"He is regarded as one of the best No8s in the world so it would be great to run up against him."
"We are expecting a physical battle again and it'll be tough.
"We need a win to keep ourselves in the championship and we'll see how it pans out."
